# defaultDepthLimit

Returns the default depth limit for instances of `NSWindow`.

```
class var defaultDepthLimit: NSWindow.Depth { get }
```

## Return Value

The default depth limit for instances of `NSWindow`, determined by the depth of the deepest screen level available to the window server.

## Discussion

The value returned can be examined with the Application Kit functions [`isPlanar`](/documentation/AppKit/NSWindow/Depth/isPlanar), [`colorSpaceName`](/documentation/AppKit/NSWindow/Depth/colorSpaceName), [`bitsPerSample`](/documentation/AppKit/NSWindow/Depth/bitsPerSample), and [`bitsPerPixel`](/documentation/AppKit/NSWindow/Depth/bitsPerPixel).
